The best definition for a macromolecules is the most abundant elements found in living cells. The correct option is d.
A macromolecule, such as a protein or nucleicacid, is a very large molecule that is important in biophysical processes.
It is made up of thousands of atoms that are covalentlybonded. Many macromolecules are polymers composed of smaller molecules known as monomers.
Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.
Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.
Macromolecules are made up of monomers, which are single units joined together by covalent bonds to form larger polymers. The most abundant elements found in living cells are the best definition for macromolecules.
Thus, the correct option is d.

Your question seems incomplete, the missing options are:
a. a trace element
b. a vitamin
c. an organic molecule necessary for life
d. the most abundant elements found in living cells
Answer:
There are no answers to choose from.
Explanation:
However, the prefix macro- means big, so the word macromolecule means large molecule. Macromolecules are also known as the molecules of life, they all contain carbon. The four macromolecules are carbohydrates, proteins, lipids, and nucleic acid. Carbohydrates are used as a quick energy source, they can be broken up into monosaccharides, dsaccharides, and polysaccharides. Proteins are used as catalyst to help speed up chemical reactions. Lipids are also known as fats, they can either be saturated or unsaturated. Nucleic acids contain information.
Examples of each:
Carbohydrate- Gluten
Protein- Lactase
Lipid- butter, or oil
Nucleic Acid- DNA or RNA
a. decreased portions sizes in restaurarts and movie theaters.
b. increased use of personal vehicles, telephones, and computers.
c. increased number of meals eaten outside the home
Answer:
c. increased number of meals eaten outside the home
Explanation:
Environment is the surrounding of living organism, where he gets to survive by meeting its needs.
Environmental factors are factors in the environment that are associated to growth and development example is temperature.
The environment an individual stays have a great influence on the physical expression and character of the individual.
For a fat person the environment had played out his role which should be controlled to achieve a significant weight loss. Increasing number of meals eaten outside the house is one major factor that would not allow such individual to loose weight. Intake of food should be greatly controlled and watched to achieve weight loss.

If the last cytosine is replaced by a guanine, the last amino acid will become tryptophan instead of cysteine.
UUG AUC CAA UGC.
UUG AUC CAA UGG.
This type of mutation that changes the amino acid is called missense mutation.
In humans, mutations of this type are responsible for diseases such as sickle cell disease. In plants, false sense mutations control, for example, the thickness of the hull of the oil palm fruit.
